If you apply for a mortgage from a building society, bank or other financial institution you will probably have to pay for a survey. You may, in addition, wish to arrange for a surveyor to carry out a full structural survey before you decide to buy.
A full structural survey will ensure that you have expert advice on the condition of the property before you buy. You would be best advised, however, to consult your solicitor or lender for more details of the likely costs.
